MFR100FTF73-634K

Through hole resistors are amongst the oldest yet most reliable and most widely used components in electrical and electronics engineering. They are devices used to limit or control the flow of electric current in electrical circuits. The MFR100FTF73-634K is a high performance through hole resistor designed for a range of applications, including power supplies, converters, motor controllers and more. This article explores its application field and working principle.

Application Field

This resistor is specially designed for use in extreme temperatures, and is capable of handling temperatures ranging from -60°C to +275°C. Its resistance range is 0.1Ω~1MΩ, and it is rated for 2W of power dissipation. This makes it well suited for applications with varying power levels, as it can handle up to 2W without any noticeable performance degradation. In addition, its dry insulation insulation can withstand up to 2500V, making it suitable for high voltage applications. Finally, its tight tolerance makes it suitable for use in precision circuits.

Working Principle

The working principle of a through hole resistor is relatively straightforward - when electric current passes through it, it resists the resulting flow, thereby resulting in a drop in the current level. This is achieved through the use of semiconductor material - usually carbon or oxides - which is fixed into place in the component. When electric current passes through the resistor, electrons in the semiconductor material become excited and resist the passage of current. With each electron resisting the current, the current level drops.

The MFR100FTF73-634K is a particularly efficient resistor, as it has been designed with several features which maximise performance. Its Resistance to heat has been optimised for use in extreme temperature environments, while its dry insulation provides high voltage operation and improved stability. The use of tight tolerance also ensures precise operation, while its low thermal EMF guarantees smooth operation and longer life.
